ifconfig is still used on BSD and, most importantly, MacOS X. Also, the Linux replacement for ifconfig is ip from iproute2, and that was made by the guy who did Linux QoS. He sort of sucks at usability. For example, `ifconfig eth0 down` becomes `ip link set dev eth0 down` and `ifconfig eth0 192.168.1.2` becomes `ip add add 192.168.1.2/24 brd + dev eth0`; I had to look these up to make sure I had the correct syntax. Okay, the actual command is `ip address add` and not `ip add add`, but it allows extreme abbreviation at the expense of discoverability.
